From the Super Mario Wiki
Tap-Tap the Red Nose is the mid-boss of World 6 in Super Mario World 2: Yoshi's Island. It was originally an ordinary Tap-Tap until Kamek cast a spell on it to make it grow gigantic. It attacks by jumping onto Yellow Yoshi, trying to hit him with its spiky body. In the room where the battle takes place, the floor is made up of rectangular blocks, which can be destroyed by throwing eggs at them. Since the large Tap-Tap is invincible to all of Yoshi's attacks, Yoshi has to defeat it by creating an gap in the floor and pushing Tap-Tap the Red Nose until it falls into the lava below.
